amrex_profiling_analyzer

This tools aims to complement AMReX's base profilng and profVis in the following aspects:

• provide easy access to profiling results
• analyze per-process time cost along critical call paths
• find where the most expensive functions are called
• detail the high-level expensive functions including what child functions it calls and their costs

Dependency

This tool is based on AMReX's base profiling. To enable base profiling, one needs to add -DAMReX_BASE_PROFILING and -DAMReX_TRACE_PROFILING while building AMReX.

The other dependent python modules (numpy, matpyplotlib, etc) can be easily installed ad-hoc.

Usage

The exemplary usages are illusrated in analyze.py.
